Deck Stats from around Rank 6: http://s32.postimg.org/pom9o2ydh/lgnd_Stts.jpg
Quick Guide (will write more extensively if there is enough demand/upvotes):
- Mulligan in a way that you ideally play something on turns one through three
- only keep secrets in opening hand if they have useful interactions (e.g. Secretkeeper + any secret; Haunted Creeper +Redemption, Knife Juggler or Steward of Darkshire + Noble Sacrifice)
- can keep Divine Favor if sure to play against priest or control warrior and the rest of the hand will be emptied fairly quickly
- face is almost never the place before Mysterious Challenger shows up
- it is the place when you have a double Secretkeeper + secret nuts hand though
- Steward of Darkshire is your earlygame MVP, always try to get some amount of value from it (amazing with Muster for Battle, Haunted Creeper, Noble Sacrifice)
- play N'Zoth as late as possible and always count for the spots left on the battlefield (I lost some unnessecary games because I had some Recruits stick around and Mr. Zoth not bringing back the right minions)
- N'Zoth also enables a less risky and more trade-heavy approach to how to handle your mid- to lategame minions. Always try to get maximum value out of everything or this will lose against "real" control decks.
- Loatheb was my flex slot here. Add Sylvanas if you face the mirror a lot, Consecration for zoo and aggro, Cairne Bloodhoof if there's a lot of warriors going around.
Since the comments section is getting a bit crowded, here's a little FAQ:
Q: Why no Dr. Boom?
The Boom Bots take up too much "space" on the N'zoth board in my experience. You really need your Belchers and Shredders to be there when you need them (remember that he also brings back your creepers). And since our board can get a bit flooded by divine shielded 1/1s, it doesn't need to get flooded by boom bots that practically do nothing after N'zoth hits anyway. This deck really needs to "win" early and mid game to be effective and a 7 drop stuck in your hand won't help that. We already run quite a high amount of end game drops anyway.
Q: Why no Shielded Minibot?
They practically take the same spot as Steward of Darkshire.
However, the deck loses quite a bit of great synergies when you remove Steward. Without her, Muster for Battle,Noble Sacrifice, and Haunted Creeper become quite a bit weaker and only really synergize with the already not that great nerfed Knife Juggler. In my experience, these synergies are what win you the mirror matches against "proper"secret paladins, zoo, and shaman (see the win ratio in the description).
